## TL;DR
Use the transitive member endpoints and follow every nextLink page. Regular member listings skip nested groups, and stopping at the first page drops the rest.

## Error
```text
(seat count 1,200; actual assignments 1,850; nested groups never enumerated; no error text)
```

## Steps
1. Confirm the gap: compare the agent's count against the admin center count. Expected: the undercount quantified.
2. Switch group member queries to the transitive variants (e.g. transitiveMembers) so nested groups resolve. Expected: nested members included.
3. Follow pagination fully: loop on nextLink until it is absent, with throttling-aware retries. Expected: every page consumed.
4. Re-run the audit and compare counts. Expected: the numbers match the admin center.

## When to use
- Audit seat counts are lower than the admin console shows
- The tenant uses nested groups heavily
- The agent paginates but still undercounts

## When not to use
- Counts are high rather than low (a double-counting problem)
- The API throttles mid-run (a throttling problem)
- Delta links expire (a sync problem)

## Tool compatibility
Microsoft Graph group and user endpoints.

### Variant phrasings
### agent uses members instead of transitiveMembers
That is the bug. Switch the endpoint.

### counts low only for one department
That department's groups are the nested ones. Verify after the switch.

## Why it happens
Graph distinguishes direct from transitive membership, and pagination is per-request. Agents that query direct members and read one page get a fraction of the real membership.
